Abstract

Trace metal advection and diffusion in natural porous and fractured materials have been investigated by using radiotracers. Three case studies are presented: (i) Se infiltration in granite cores in the presence of pyrite; (ii) Co advection in quartz sand columns containing a layer of MnO(2); (iii) Cr diffusion in clay. It is shown that the migration processes are controlled by surface mediated redox transformations.
